Jupiter Inlet - surf spot statistics

Jupiter Inlet offers surfable conditions year-round, but the best windows for quality waves are typically during the fall and winter months, from October through March. During this period, the swell activity is more consistent, with a higher percentage of ground and wind swells compared to summer. October and November stand out as the peak months, featuring the largest mean swell size (0.9m–1.0m) and a solid mix of ground (16–17%) and wind swells (64–69%), providing better wave energy. Wind conditions, while still predominantly onshore (bad winds 85–88%), see slight improvements in favorable wind days (12–15%). Winter months like December and January also deliver decent swells, though slightly smaller (0.8m), with similar wind challenges. Spring (March–April) sees moderate swell activity, but summer (June–August) is the least favorable, with minimal ground swells, weak wind swells, and very poor wind conditions (95–98% onshore). If you’re aiming for the most rideable days, prioritize late fall and early winter when swell consistency, size, and marginally better wind odds align. Summer is mostly flat or blown out, while spring offers occasional opportunities but lacks the punch of the colder months.

November at Jupiter Inlet offers fairly average surf conditions with moderate consistency. The average swell height is around 1.0m with a decent 8.5s period, providing rideable waves, though they tend to be on the softer side. The dominant swell direction comes from the ENE, which aligns best with the spot, producing the most frequent and cleanest waves in the 0.5-1.5m range (roughly 60% of the time). Larger swells over 1.5m are less common but do occur, mostly from NE and ENE directions. Wind conditions are a mixed bag—only about 15% of the time are winds ideal (light offshore or cross-offshore), while ENE and NE winds prevail, often blowing in the 10-30kph range, which can create chop. Early mornings or wind-protected sections may offer cleaner sessions. Overall, expect small to mid-sized waves with occasional clean peaks, but be prepared for variable wind influence. Not a standout month, but there are surfable days if you time it right.
